Answer:
A
Explanation:
The pesticides and chemicals in are food could get us seriously sick and cause food poisoning. We are hurting our water by dumping sewage water into lakes and rivers did you ever think that someday a river or a lake will mix in with the ocean.
Because the whole west coast is on the "ring of fire" witch has high volcanic activety and junk like that
We are using the General gas equation P x V/K = P x V/K
1. P = 1atm V=500ml so PxV= 500 at 6.5km P = 0.5atm V = ? so P xV = 0.5 x V
(We don't have to worry about temperature!) 500 = 0.5 x V so V = 1000ml
2. NO CHANGE in pressure here so we have V/K V=2.75 K = 20 + 273=293 so V/K= 2.75/293
Next set V = 2.46 K = ? so V/K = 2.46/K then 2.75/293= 2.46/K so K=(293/2.75)x2.46
=262 K
Convert back to Celsius 262 - 273 = -11 C
It's raining so I have to rescue the laundry!
Laundry rescued!
3.Now we have to use all three variables. I am using 273K and 100kPa for STP.
P = 100 V = 700 K = 273 These are altered P - unknown, V = 200 K = 273+30=303
!00 x 700/273 = 256.4 this is equal to P x 200/303 = P x 0.66
so P = 256.4/0.66 = 388.48kPa
Answer: isotopes are two or more atoms of the same element having the same atomic number(proton number) but different mass number due to the difference in their Neutron number
